There are hints of it though. I noticed in my most recent data dump there was a list of "contacts." Some of those were people who I was never Facebook friends with and included contact information (e.g. alternate emails) that I never had.

It seems like this data was built off of people's phone contact lists. It definitely seems like my contact list was the root of mine.
